Causes of the ‘System 5 Error Has Occurred’ Message
Most people are surprised when they see the “System error 5 has occurred” error when using the Windows command prompt, because most commands don’t require administrator access. However, if you ever do try to use one of those administrator commands, this problem will arise.
It’s the equivalent of an “Access is denied” error. If you try typing a command like “net user,” which requires elevated (administrator) access, you’re going to see the system error 5 message. This message can occur even when you believe you have administrator rights on the computer.
How to Fix System Error 5 on Windows
The simplest solution for a System 5 error is to run the command prompt as an administrator. Here’s how to do that.
The easiest solution is to launch the command prompt as an administrator. Select the Start button, type “Command Prompt,” then right-click Command Prompt, and select Run as administrator. There are other methods you can use to launch the command prompt with elevated access. If you have User Access Control enabled on your system, you’ll see a prompt requesting permissions to make changes to the system. Select Yes to continue. Now, when you type the same command that requires administrator level control, the command will finish without the system error 5 message.
Disabling User Access Control
If you don’t want to deal with the annoying UAC message box, you can disable User Access Control.
Open the Start menu, type “UAC” into the search bar, then select Change User Access control settings. In the User Account Control Settings window, move the slider down to Never notify. Select OK to finish. Once User Access Control is disabled, you won’t have to deal with the pop-up warning to allow the command prompt access to make changes on your system.
